MACHINE FOR MAKING ROOFING-TILES.

SPECIFICATION forming part of Letters Patent N 0. 558,326, dated April 14, 1896.

Application filed January 4, 1893. Serial No. 457,262. (No model.) Patented in Germany October 23, 1889, No. 49,238, and May 6, 1890, No- 51,940, and in $witzerland March 16, 1893,1l0. 6,743.

To all whom it may concern.-

Be it known that I, KARL THOMANN, a subject of the German Emperor, and a resident of Halle, Germany, have invented a new and useful Improved Machine for Making Roofin g-Tiles, (for which I have obtained German patents, No. 49,238, dated October 23, 1889, and No. 51,940, dated May 6, 1890; and a Swiss patent, No. 6,743, dated March 16, 1893,) of which the following is a specification.

This invention relates to a machine for shaping roofing-tiles made of trapezoidal form and provided with a top flange that extends along two sides of its face and with a bottom flange that extends along the two opposite sides of its bottom. The upper flange of one tile will interlock with the lower flange of the adjacent tile, as will be readily understood.

In the accompanying drawings, Figure 1 is a vertical longitudinal section of the machine for producing the tiles; Fig. 2, a top view thereof; Fig. 3, an enlarged vertical longitudinal section through. the hopper; Fig. 4, a similar section with the parts in a different position; Fig. '5, a similar section with the parts in a still different position; Fig. 6, a section through the tile when completed, and Fig. 7 a similar section after the tile has been shifted previous to the removal from the false bottom.

The letter A represents a mold provided with false bottom B, that can be raised by means of treadle D, and rods J 'H to discharge the tile. The mold A is free to be moved in a horizontal direction beneath hopper E, or the hopper may be moved over the mold, as may be preferred. The hopper E is provided with an inner inclined shaper or core F, between which and the wall of the hopper the flange a of the tile is formed. The core F may be raised or lowered obliquely by means of a tooth-segment G, that engages an inclined rack on the core.

In order to cut off the composition at the proper height, I employ a horizontally-sliding cutter M. The false bottom 13 should be provided with a groove and notch corresponding to the lower flange band nose N of the tile, so that these parts, together with the body of the tile, will be molded by pressing the plastic material into the mold A by hand. The mold containing the tile thus partially formed is then moved beneath hopper E, the core F is lowered,and the plastic mass is packed upon the upper side of the tile to form flange a, Fig. 3. Next the cutter M is projected into the hopper to cut off the flange at the proper height, and then the core is raised to liberate the flange, Fig. 4. During the raising of the core the cutter M will project over the flange and prevent the same from being broken. The mold A is now drawn back, Fig. 5, into its original position, the false bottom B is raised, and the completed tile is removed.

If the flange b is to be undercut, a wedge K is placed against a shoulder of the false bottom, and against this shoulder the nose N is molded. This wedge may also serve to form a groove in said nose. After the wedge has been withdrawn through a lateral opening-7c the tile can be shifted upon the bottom B to liberate its undercut edges previous to raising the tile off the bottom.

What I claim is 1.. The combination of a mold with a false bottom having a shoulder at each end, one of said shoulders being undercut, and with a wedge adaptedto be placed against the opposite shoulder and to cooperate with the undercut shoulder in the removal of the finished tiles, substantially as specified.
